Abstract:
The structural design and rigorous analysis of a foundation system supporting dynamic equipment is complex. Therefore, designers often follow rules of thumb for their design. These rules of thumb, however, may lead to oversized foundations. To optimize slab size while avoiding resonance and ensuring minimal human perception of vibrations, practical guidelines and recommendations for design are presented. The effects of changes in foundation dimensions, operational speed of the equipment, and modulus of subgrade reaction on a slab’s natural frequency and peak displacement are also discussed.
